Comment (by chrstphrchvz):

 I notice that at least some of these ports
 [https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/28589/steps
 /install-port/logs/stdio build successfully on 10.7] where MacPorts' clang
 9.0 is used instead of Xcode clang. I have [https://github.com/macports
 /macports-ports/pull/8184 opened a PR] to avoid compiling with known-non-
 working versions of Xcode clang (8.2.1 and earlier; the earliest known
 working version I'm currently aware of is 9.2).
